い。BACKGROUND OF THE INVENTION Roofing usually has roofing paper glued and nailed one above the other in several layers as a roof covering. For protection against heat, roofs of this type are often covered with a layer of gravel, which has a heat-insulating effect. Repeated visual inspections are performed by roofers to identify leaks in roofs. Roofers often begin by searching for and peering into areas where they suspect leaks occur frequently, based on their own experience. Locating the leakage point in this way is difficult to realize, especially in the case of roofs with a gravel layer. This is because the leak point is covered with a layer of gravel, which must be removed. Furthermore, if the leakage point is relatively small, it often takes a full day to find the leakage point, even on a rough roof without a gravel layer.

In order to measure the pulses that are guided through the damp roof from the leakage point through the wet path through which the roof is exposed, the roof roof is probed by a measuring detector, which is moved from the leakage point to the wet roof. It is operatively connected to a measuring device which measures the pulse amplitude which gradually decreases towards the edge of the roof.

るようになる。Operation and Effects The method of the invention applies electrical pulses from a pulse generator to the damp path from the wet spot to the leak spot and the roof. The pulse has maximum pulse amplitude at the leak location. The magnitude of the pulse amplitude decreases as one approaches the edge of the roof.
A person with a measuring device for measuring pulse amplitudes can therefore probe the roof with the measuring detector and measure the pulse amplitudes, which gradually increase towards the leak location. The person involved in the task then moves in the direction in which the magnitude of the pulse amplitude value indicated by the measuring device is maximum. That is, the person actually follows the pulse amplitude, which increases towards the leak point, until the leak point is found. With this simple and advantageous means, leak locations can be found relatively quickly and easily. The method of the invention reduces the number of personnel required to locate leaks to a minimum and allows roof repairs of low-temperature roofs to be carried out at a significantly lower cost.

箇所の位置を迅速に検出することができる。 If the roof does not have a hole, the present invention connects the negative terminal of the pulse generator to a bare cable provided on the roof. Thereby, by simple means, the electrical circuit from the positive terminal to the negative terminal of the pulse generator is also closed, so that it is possible to apply pulses even to metal potholes, and thus this In this case, the location of the leakage point can also be quickly detected.

改善される。 The device for carrying out the method according to the invention is such that the pulse generator is configured to generate direct current pulses and the measuring device mutually adjusts the pulse amplitudes supplied to the measuring device via a measuring detector (measuring sensor). They are compared and the larger pulse amplitude is indicated by a pointer device (pointer indicating instrument or pointer type display device) having a central indicator. The center indication of the pointer device indicates to the pointer a pulse amplitude that increases as it moves toward the leakage location, and the operator must adjust the pointer's deflection until it reaches its center or reference position. All you have to do is follow the direction. The center position is the leakage point. This is because in the area of the leakage point, the magnitude of the pulse amplitudes is approximately equal, so that the measuring device is supplied with the same pulse amplitude, so that no pointer deflection occurs in the pointer device. Also, by that,
Locating leaks in roof roofs becomes easier and improved.

中心位置に留まる。 In another embodiment of the device according to the invention, the measuring sensor is constructed of a partially insulated aluminum bar, each of which is connected to the base of two transistors that are connected to form a differential amplifier circuit. and the emitters of these two transistors are interconnected via a pointer device. The relatively small pulse amplitudes obtained from the measuring sensor are therefore amplified by the transistor and then fed to the pointer device, so that the pointer device always receives a correspondingly amplified pulse amplitude by means of the differential amplification circuit of the transistors. can swing left or right, or stay centered if the pulse amplitudes are equal.

る。 A house 1 has a wet area 2. This was caused by water entering from a leak in the flat roof 7. The positive electrode 4 of the pulse generator 3 is connected to the moisture leakage point. The negative pole 5 of the pulse generator also leads through a window 6 to a flat roof 7 and is connected to a bare cable 8 arranged around this flat roof. The pulse generator is connected to the house's power supply. When the pulse generator 3 is connected, a DC pulse is generated. The DC pulse reaches the water leakage location from the wet location 2 via the water leakage path,
From there, moisture or damp reaches the bare cable through the flat roof itself. Therefore, it is fed back to the pulse generator. In other words, a current circuit is formed here.

The measuring device 9 has a pointer-type display device 11, and the pointer moves left and right from the center. Pointer type display device 1
1 is operatively connected to the circuit shown in FIG. Then, depending on the magnitude of the measured pulse amplitude,
The pointer swings to the left or right. The maximum value of the measured pulse amplitude is displayed by the deflection of this pointer. Therefore, at the same time, it is possible to know the direction of the pulse amplitude, which increases toward the water leakage location.

きさが同じだと、指針は振れない。 The pointer type display device 11 is connected to the emitters of two transistors T1 and T2 in the differential amplifier circuit. The bases of both transistors are connected to a measuring element (measuring detector) 10. Therefore,
The pulse amplitude detected by the probe 10 is supplied as an input signal to the transistors T1 and T2, where it is amplified and then sent to the pointer type display device 11 in the emitter circuit. The display device 11 measures the current from the interconnected emitters of the transistors T1 and T2. The pointer then swings to the left or right depending on which transistor supplies the stronger current. If the magnitude of the two currents is the same, the pointer will not swing.

制御することができる。 When the measuring device 9 is connected, via the collector resistor R9 and the controllable resistor P1,
The pointer of the pointer type display device 11 can be adjusted to the center position. Furthermore, two diodes D1 and D2 are arranged in the input circuit, and these diodes protect the transistors T1 and T2 from overvoltage. Furthermore, pre-resistors R1 to R4 are arranged in the input circuit. This preresistance allows the sensitivity of the measuring device to be adjusted. This differential amplifier circuit is also supplied with 9V DC voltage from a dry cell battery. A probe T is provided to inspect the state of charge of the dry battery. This probe acts via a resistor R10 so that the pointer of the display device 11 swings when the dry battery is sufficiently charged. Resistors R5 and R6 are transistors T1,
This is the emitter resistance of T2. The bases of both transistors are grounded via resistors R7 and R8.
Therefore, it is possible to control the balance of transistors or differential amplifier circuits.
